What happens when Lay is left with nothing but a box that has left him heartbroken? In his time of dispair, he never imagined he would be able to get through it. But after a couple of weeks, he meets Mihi who is able to pull him back up to be the man he use to be and heal the hole in his heart in such a short period of time.

Everything was great with her, his friends, and family until his ex-girlfriend, Ziying, decided to make an appearance in his life again. This time she did not come to play Miss. Little-nice-girl, but instead is here to win him back. Torn between two women, Lay doesn't know what to do. He finds himself loving Mihi yet his feet always leads him back to Ziying. Unknow to him, his roomate, Chanyeol, had fallen in love with Mihi and plans on never leaving her.

Will Lay leave everything he had work so hard to recover in that time of dispair behind and leave with the one that had hurt him in the past? Or will he risk everything to get the one that had always been there for him back?

Just when life couldn't get any better, Kai's childhood friend, Yoonnae, magically reappears into his life, driving a wedge between his girlfriend and him. Seulhae feel threatened by her presence finding her best friend, Chanyeol, to be her only ally. Blinded by the problem of the same difference, their love continues to grow apart.

Kai will not see it through until she understands his feelings for Yoonnae. But how can she when he does not see hers for Chanyeol. Unable to come to a consensus, she pulls herself away from the person most dearest to her, yet he persists to mend this relationship even when she no longer wants to hold his hand and grow together.

Later Seulhae finds out that her mother had engaged her to her bestfriend's son, Chen. Her family in no way will support her feelings for Kai. Forced to become the globally golden actress, will Seuhae accept her so called predestined future and continue a life of falsification? Or will she break through and fight for the future she knows well Kai and she can share?

A love that knows all bounds lurks in Yoonnae's shadow as she faces two of the biggest delimas in her life, family or love. Her brother, Yunho opposes her love for Kris greatly as her cousin, Jessica, won't give him up without a fight. Taemin, her so called guardian angel, confuses her when he starts showing more affection than usual. Pressured by her loved ones, she takes a step back and allows her feelings to be unheard, unexpressed, and insincere.

But Kris knows better. Her mind may restrict her love for him but her heart won't lie. Their souls are bind as one and he feels it. But why can't anyone see it? Why must Kris give up the love he deserves. The love he has earned with termendous sacrafices. Just how much more does he need to do to prove he's worth her love?

A love that should not be tainted. A stong bond which should not be broken. An unconditional sacrifice for one another. A deeper magic within ones self to be shared with only one person. This is true love. But will Kris be able to hold onto Yoonnae, who's willing to give up everything for the greater good? Or will he fullfil her farewell wish by loving Jessica in her place?

Surrounded by multiple fragil love resting on a thin line, both Yoogeun and Wenxin find themselves in the utter most troublesome situations. As young as the two are, they both know what's right and what's not. It pains their heart when they see the ones they love soaked in tears and dragged by misery. Distraught by these broken couples, these two kids set a goal and takes on a mission to keep the couples together.

Yoogeun takes steps to help his teacher, Mihi, mend her love with Yixing as well as trying to clear the confusion between Seulhae and Kai, yet there seems to be no progress as the days go by. Wenxin, on the other hand, tries his best to support his brother, Kris, in wanting to love Yoonnae, but he can barely keep up due to so many people opposing their love.

With the influences of the SM family, the table turns, opposing Yoogeun and Wenxin's tatics. Friends or foe, the two find it quite difficult to bind the couples together. Realizing this, they've come to the conclusion that not everyone is destined to a happy ending. You win some. You lose some. Now they must make a decision on which love they will choose to save and which ones they must abandon. Will Yoogeun and Wenxin save the love that involves their loved ones, or will they save the love that is deserving?
